My website was hacked on Mar. 7 or 8 by some culprit who used what's known as the "zbind exploit." I found a file named "za.tgz" on my server, and inside its folder were two executable files named "zbind" and "zero." When you used "www.(mydomain).com" you'd be taken to some crap with only three URLs, but when you didn't use the "www" in the URL, the site would work normally. My site is hosted by Yahoo Small Business and they were great in helping to get the site working properly again, they deleted the command that was causing this.

I was just wondering if anyone is familiar with this "zbind" thing, and what steps I could take to prevent this from happening in the future.
